[Samba] Kerberos-related configure script problem on Solaris with3.2.0

I'm building samba-3.2.0 on a Solaris 10 x64 box using the Sun Studio
cc compiler.

I'm running into a problem. I have a workaround. Let me know if I
should post a bug report.

A. The problem:

$ ./configure --prefix=/usr/local/samba-3.2.0 --with-ads --with-pam
--with-acl-support --with-shared-modules=idmap_ad
--enable-socket-wrapper --enable-nss-wrapper
--with-krb5=/usr/local/heimdal/heimdal-1.1

....

B. The immediate cause of the problem:

What's causing the #error: UNKNOWN_KRB5_ENCTYPE_TO_STRING_FUNCTION is
that with Heimdal, configure should be setting
HAVE_KRB5_ENCTYPE_TO_STRING_WITH_KRB5_CONTEXT_ARG in config.h, but it's not:

$ grep HAVE_KRB5_ENCTYPE_TO_STRING include/config.h
#define HAVE_KRB5_ENCTYPE_TO_STRING 1
/* #undef HAVE_KRB5_ENCTYPE_TO_STRING_WITH_KRB5_CONTEXT_ARG */
/* #undef HAVE_KRB5_ENCTYPE_TO_STRING_WITH_SIZE_T_ARG */


C. The root cause of the problem:

The configure script test for the right form of
krb5_enctype_to_string() is failing because <stdlib.h> isn't #included
in conftest.c, and as a result free is not found:

configure:62117: cc -o conftest -errwarn=%all
-I/usr/local/heimdal/heimdal-1.1/include -D_LARGEFILE_SOURCE
-D_REENTRANT -D_FILE_OFFSET_BITS=64 -Iinclude -I./include -I. -I.

cc: acomp failed for conftest.c
configure:62120: $? = 2
configure: program exited with status 2
configure: failed program was:
....
| /* end confdefs.h. */
|
| #include <krb5.h>
| int main(void) {
| krb5_context context = NULL;
| char *str = NULL;
| krb5_enctype_to_string(context, 1, &str);
| if (str) free (str);
| return 0;
| }


D. The Workaround:

Put "#include <stdlib.h>" after "#include <krb5.h>". The configure
script will correctly detect and set
HAVE_KRB5_ENCTYPE_TO_STRING_WITH_KRB5_CONTEXT_ARG, and the build will
succeed.

This was already fixed by Andrew Bartlett in the v3-3-test
branch. Sorry that it did not get merged for 3.2.1, will be
in 3.2.2.
http://git.samba.org/?p=samba.git;a=...f;h=91c17ecfd7
gets you to the patch after which you will have to run
./autogen.sh

No worries. Just wanted to point it out it in case it had gone
unnoticed. Thanks.
